Asymmetric phase transitions in random noncommutative geometries
Benedek Bukor, Masoud Khalkhali, Samuel Kováčik +4
In this paper, we study the asymmetric phases of the quartic type (0, 1) and (1, 0) Dirac en- sembles via three approaches: the Riemann-Hilbert approach, bootstrapping with positiv…

Accretion, mergers, and metastability of fuzzy spheres in a three-matrix model
M. Hrmo, S. Kováčik, K. Magdolenová +5
A three-matrix model that contains a plethora of fuzzy sphere solutions was defined twenty years ago. It has been shown that in a certain regime of the model, combinations of fuzzy…

Eigenvalue distribution from bootstrap estimates
Samuel Kováčik, Katarína Magdolenová
The bootstrap method has proven useful for a wide range of matrix models. Here, we show that the computed momenta can be used to reconstruct the underlying eigenvalue probability d…
